Title: Improvements in or relating to methods and apparatus for making elastic yarns
IPC: D02G3/32
Filed: 1932-06-26
Abstract: 395,521. Covering elastic cores by winding. REVERE RUBBER CO., 355, Valley Street, Providence, Rhode Island, U.S.A.-(Assignees of Cobb, H. Z. ; 236, Butler Avenue, Providence, Rhode Island, U.S.A.) July 26, 1932, No. 21087. Convention date, Aug. 14, 1931. [Class 109.] In making elastic yarns, the core is fed uniformly and tensioned uniformly by means of let off devices 2, 10 and take-up devices 25, 27 and whilst thus tensioned is covered at 13, 15 respectively with oppositely-inclined helical windings of cotton, wool, rayon, silk, or linen &c., after which the covered core is wound under relaxed tension on a reel 29 driven by a roller 31. The core supply roller 2, the heavy nipping roller 25 of the take up device, and the reel 29 are supported by brackets on connected rods 7, 28 so as to rest on their driving rollers 10, 27, 31 and rotate at constant linear speeds, the roller 27 rotating 2 or 3 times as quickly as the roller 10 so as to tension the core. The lower and upper core covering devices are similar, the latter comprising a spindle 15 furnished with a motor and with a hollow spool from which the yarn passes on to the core through travellers 19, 23 on rings 20, 22 on a fixed cover plate 21 and on the spindle 15 respectively. Or the yarn may merely pass through the traveller 19. The upper and lower spools may rotate at the same or different speeds and may carry the same or different covering materials. On raising the rod 7, the reel 29 and the rollers 2, 25 are lifted from their driving rollers. Collars 35, 36 on the rod operate levers 38, 38 which actuate spring-controlled brakes for the motors driving the covering devices, and a channel part 37 operates a switch controlling the supply of current to the motor. In a modification, the elastic core 1<1>, Fig. 3, is fed from a supply 43 by nipping rollers 46, 47 and is taken up by similar devices. The covered core is laid evenly on the reel by passage through a pigtail on a traverse bar 33, Fig. 1. A binding thread woven into the covered elastic yarn bv means of a slot on the reel separates the wound mass into groups and it is then tied, after which the mass is removed in the form of a skein. Specification 385,483 is referred to.

Title: Process for prolonging the film-forming life of normally crystalline polymer latex
IPC: C08J3/03
Filed: 1954-07-22
Abstract: The film-forming life of a latex of a normally crystalline vinylidene chloride polymer is prolonged by addng to the latex, before it has lost its film-forming ability, from 2 to 10 per cent, based on the weight of dispersed polymer solids, of an organic solvent or an organic solvent mixture which exerts at least a swelling action on the polymer, does not coagulate the latex, and is at least as volatile as water.  The solvent may be tetrahydrofuran, methanol, ethanol, isopropanol, dioxane, carbon tetrachloride, methylene chloride, chloroform, or ethylene chloride.  A thickening agent such as methyl cellulose.  Irish moss and karaya gum may also be incorporated in the latex.  The latex may be prepared by polymerizing the monomeric materials in an aqueous phase containing a catalyst such as potassium persulphate and an emulsifier such as a sodium alkyl sulphate, and the solvent may be incorporated in the latex before or after polymerization.  Examples describe the production of latices of vinylidene chloride-acrylonitrile and vinylidene chloride-vinyl chloride copolymers.

Filed: 1920-07-20
Abstract: 170,408. Dickinson & Co., Ltd., J., and Hawdon, F. G. July 20, 1920. Envelopes, making. - Relates to envelopemaking machines in which the finished envelopes are fed to a drying and delivery device consisting of pockets formed on the links of m endless chain. The invention consists in driving this device from the main drive of the machine, and in providing means for transferring the drive to a secondary drive, when the envelopeforming mechanism, &c. is stopped, in order that the chain may be cleared of envelopes without driving the gummers, folders, &c. In the construction shown in plan in Fig. 2, the machine is driven by a clutch pulley 14 mounted on a shaft 1 and this shaft is connected bv gearing (not shown) with a ratchet wheel 27 which is mounted on and drives a shaft 3 geared with a shaft 4. This shaft 4 drives the chain shaft 8 and shafts 12, 13 of supplementary motions. The clutch pulley 14 is connected by means of sprockets 16, 17 and a shaft 20 with a second ratchet-wheel 24, which is mounted on the shaft 4. The gears are so arranged that, when the pulley 14 is clutched to the shaft, the machine is driven through the wheel 27, the wheel 24 rotating at a slower speed than the shaft 4 and thus running free. When the pulley 14 is declutched, the shaft 1 ceases to rotate and the pulley continues to drive the chain shaft 8 and the shafts 12, 13 through the ratchetwheel 24, thus allowing the chain to be cleared without driving the folders, gummers, &c.

Filed: 1920-07-21
Abstract: 167,672. Imray, O. Y., (Sieber Products Manufacturing Co.). July 21, 1920. Flexible band files; locks; covers.-In loose-leaf binders of the type comprising tapes, bands, or cords connected with a winding-shaft, the winding-shaft is mounted in two or more bearings each consisting of a detachable unit, one unit carrying the locking-mechanism and the others movable relatively to the main unit according to the number of, and space between, the tapes &c. employed. The main unit F, which is not directly connected with the auxiliary units, has a leafclamping portion 1 with bearings 2 for the winding-shaft and a slot 3 through which the tape passes. The auxiliary units, one of which. F<1>, is shown, have also a leaf-clamping portion 1<a>, bearings 2<a> and slot 3a. The units are detachably connected with the cover preferably by a flexible hinge 4 having a reinforcing-rod 5 over which the units may be crimped. The other ends of the tapes are connected to the clamping-bar E which has a flexible hinge connection 4a with the cover. The locking-mechanism, which is of the spring-urged tubular ratchet type, has a ratchet-wheel 7 having a pin-and-slot connection at one end of a rod 10 situated in a groove in the winding-shaft, the other end of the rod being connected with a sliding-collar 11. The stationary member 8 of the ratchet elements has a bifurcated portion 15 which engages a notch 16 in the unit F. The operating - key G has a tubular portion 12 slotted as shown at 13 for engagement with a pin 14 on the winding-shaft, the ends of the key and collar 11 having a tapered engagement. Initial rotation of the key to the left causes the pin 14 on the winding-shaft to engage the slot in the key and force the collar along the shaft, thus disengaging the ratchet elements, continued movement of the key in the same direction slackening the tapes. Rotation in the reverse direction causes a shoulder 13a on the key to abut against the pin 14 and tightens the tapes, the ratchet mechanism remaining silent during the slackening and snapping over the teeth when tightening.
